Plot the estimated Qini curve.

Source: R/plot.R

Plot the estimated curve \(Q(B), B \in (0, B_{max}]\). If the underlying estimated policy \(\pi_B\) entails treating zero units (that is, all the estimated treatment effects are negative) then this function returns an empty value.

# S3 method for maq
plot(
  x,
  ...,
  add = FALSE,
  horizontal.line = TRUE,
  ci.args = list(),
  grid.step = NULL
)

Arguments

x

A maq object.
...

Additional arguments passed to plot.
add

Whether to add to an already existing plot. Default is FALSE.
horizontal.line

Whether to draw a horizontal line where the Qini curve plateaus. Only applies if the maq object is fit with a maximum budget that is sufficient to treat all units that are expected to benefit. Default is TRUE.
ci.args

A list of optional arguments to lines() for drawing 95 % confidence bars. Set to NULL to ignore CIs.
grid.step

The spend grid increment size to plot the curve on. Default is max(floor(length(path.length) / 1000), 1) where path.length is the size of the grid underlying the estimated Qini curve.
